Maintenance
Warning:
Never use fl ammable air duster or other materials when cleaning the air-fi lter. Flammable substances may ignite
causing fi re or backdown when the lamp is illuminated.
Do not use fl ammable solvents (benzene, thinner, etc.) and fl ammable aerosols when cleaning the projector body
and lens. Flammable substances may ignite causing fi re or breakdown while the lamp is illuminating.
Caution:
Be sure to turn off the lamp and unplug the power cord from the wall outlet before you perform any maintenance on
the projector.
Cleaning of the air-fi lter
Clean the air-fi lter frequently (about once a month). If the fi lter or ventilation grilles become clogged with dirt or dust,
the temperature inside the projector may rise and cause troubles, such as damage to the inside parts and shortening
the life of the panels.
When the temperature inside the projector rises, the STATUS indicator will blink orange and the lamp will be turned
off.
1. Raise the lock of the fi lter cover in the direction of the arrow.
2. Remove the air-fi lter.
3. Wash the air-fi lter or change it with a new fi lter.
Use water or diluted mild detergent to clean the fi lter. Rinse the fi lter thoroughly
and let it dry completely.
4. Attach the air-fi lter.
5. Attach the fi lter cover to the projector.
Make sure that the air-fi lter is attached correctly without
displacement.
Important:
If the fi lter is damaged or becomes extremely dirty, change it with a new fi lter. Contact your dealer for a new fi lter.
Use the dedicated fi lter only.
Caution:
Be sure to use the projector with an air-fi lter. If not, dust may get inside the projector causing fi re and failure.
Cleaning of the projector and the ventilation slots
Use a soft cloth to clean the projector and the ventilation grilles. When the grilles become dirty, wipe them with a soft
cloth dampened with diluted mild detergent, and then wipe them with a dry cloth.
To protect the surface of the projector from fading or deteriorating:
Do not spray insecticide on or inside the projector.
Do not use benzine or thinner to clean it.
Do not let rubber or plastic materials contact with projector.
Cleaning of the lens
Use a standard lens-cleaning brush or a piece of lens tissue dampened with lens cleaning fl uid. The lens surface is
fragile. Use only recommended, nonabrasive lens-cleaning materials. Do not touch the lens with your fi ngers.
